a 0.27kg marble collides with a 0.19 blue marble before the collision the red marble had a velocity of 2.5m/s and ther blue marble was at rest after the collision the blue marble had a velocity of 2m/s what was the velocity of the red marble after the collision

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west

answer: 31, 5556. 952 seconds
